* Introduce HsaKFDContext structure and infrastructure for multiple KFD contexts, enabling
independent contexts within a single process.
* Refactor core components (queue, event, FMM, topology) to be context-aware,
using explicit HsaKFDContext parameters instead of global state.
* Replace global hsakmt_kfd_fd with context-specific file descriptors, ensuring full context isolation.
* Maintain backward compatibility by redirecting legacy APIs to use the primary context.
This refactoring establishes a foundation for multi-context support while preserving existing functionality.

* libhsakmt: Update hsakmt_fmm_get_handle to support address range
Currently, hsakmt_fmm_get_handle works only if the address is allocated
(staring) value. Update it so it can find the handle if address falls in
the valid allocated range. This is useful for AMD infinity storage
feature where data needs to be transferred to any memory within in the
allocated range

* libhsakmt: Introduce AMD Infinity Storage (AIS) API
Add hsaKmtAisReadWriteFile() API to support AMD Infinity Storage. The
API moves data directly from GPU VRAM to a file.
v2: Add in/out ioctl arguments to provide more status information to
user space. Modify hsaKmt API also accordingly.

* rocr: Initial implementation of AMD Infinity Storage (AIS)
Implement first two API: hsa_amd_ais_file_write and hsa_amd_ais_file_read
v2: Change API from hsa_amd_ to hsa_amd_ais_
Change API to take in handle instead of fd for compatibility accross
different platforms
